DETAILED DESCRIPTION

Referring to FIG. 1 and FIG. 8, the present invention comprises a location services facility that may provide services or data products associated with a geolocation datum 104 associated with a portable electronic facility 300. The location services facility may comprise a database 100 containing aggregate data 102, an application server 108, and a Web server 110. The location services facility may provide the aggregate data 102, in raw or processed forms, to a third-party service provider 200. In some embodiments, the present invention may comprise a network 304, which in some embodiments may be a peer-to-peer (P2P) network, comprising a plurality of facilities wherein each of the plurality of facilities may be a portable electronic facility 300 across which may be distributed the database 100, or its equivalent or constituent components 302, containing, in whole or in part, the aggregate data 102. An expanded view of one aspect of the P2P network is shown in FIG. 3. These embodiments are discussed in detail below and other embodiments will be apparent from the following discussion.

Referring to FIG. 4, the disclosed invention may gather a datum 104 from a portable electronic facility 300. The datum 104 may be stored in the database 100. In particular, the datum 104 may be representative of a position and/or velocity associated with the portable electronic facility 300. Alternatively or additionally, the datum may be representative of an output value from a sensor associated with the portable electronic facility 300. In most cases, an additional datum 104 from the portable electronic facility 300 or another portable electronic facility 300 may also be stored in the database. The aggregate of a plurality of datum 104 from one or more portable electronic facilities 300 may comprise aggregate data 102, which may be stored within the database 100.

Referring again to FIG. 1, the aggregate data 102 may flow from the database 100 to the application server 108. The application server 108, in turn, may provide an application based service, a number of which are described below and the general provision of which further comprise the disclosed invention. The application based service may be provided to a user of the portable electronic facility via a Web interface such as a Web browser. In this case, embodiments may comprise the Web server 110 for delivering the service.

Referring to FIG. 2, the aggregate data 102, in whole or in part, may be provided to a third-party service provider 200 in a predetermined format, which may be specified by an XML schema. As provided, the data may be formatted or modified according to various needs, including without limitation a need of a first end user 202 who may be a data consumer (such as, revealing consumer behavior); a need of a second end user 204 who may be a user of the portable electronic facility (such as, obeying a privacy agreement associated with the data); and/or a need of the third-party service provider 200 (such as, receiving data in a file that is formatted to facilitate automated processing). When formatted, the data may comprise a report, which may be a computer generated report.

The third-party service provider 200 may in turn provide a service to the first end user 202 or the second end user 204, wherein the service may be associated with the data. In some cases, the first end user 202 may be a marketing organization. Other cases will be apparent due to the following description.

In one embodiment, the aggregate data 102 may be disaggregated and provided to the third-party service provider as a single data point. This may be useful in many applications including, but not limited to, a service that provides to the end user a map showing the location of the user and the user's immediate surroundings; a service that provides to the end user a map showing the location of a point of interest in the vicinity of the user; a service that provides to the end user a map showing the location of another user; a service that provides to the end user a map showing the location of a pet associated with the user, wherein the pet may be fitted with a collar containing a portable electronic facility; the establishment of a geofence (described below in detail) and the monitoring of the portable electronic facility with respect to its crossing the geofence; and so forth.

In another embodiment, the aggregate data 102 may be scrubbed and provided to the third-party service provider 200 as a generalized dataset. This may be useful in many applications including, but not limited to, a service that may provide to a marketing company demographic information that may be representative of the generalized dataset, which may be representative of a plurality of users in a given geographical area; a service that may provide the user with highway traffic information that may be based upon aggregate traffic flows, which may comprise the generalized dataset; and so forth. For example and without limitation, in one application, the generalized dataset, which may comprise demographic information, may be representative of users' gender and spending habits, wherein the spending habits comprise the means and routes utilized by the users to arrive at a shopping destination. The generalized dataset may further comprise a unique identifier associated with each user represented, wherein the unique identifier may obscure the identity of each user white also allowing the third-party service provider 200 to discriminate between users, especially during an analysis of the generalized dataset.

In yet another embodiment, the aggregate data 102 may be provided in its entirety to the third-party service provider 200 as a comprehensive dataset. This may by useful in many applications including, but not limited to, a service that may provide to a logistics company detailed tracking information pertaining to a fleet of delivery vehicles, wherein each vehicle is located and tracked through time; a service that shows to a head of a household a plurality of locations representative of each of the members of the household; and so forth, For example and without limitation, a company providing cleaning services may utilize the aggregate data 102 to track how long its employees dwell at each customer location and which routes the employees take to travel to each customer location. This information may be useful in monitoring the efficiency of its employees and in optimizing assignments given to employees, for example and without limitation, by grouping jobs given to a particular employee into a smaller geographical area.

In still yet another embodiment, the aggregate data 102 may be processed to provide a service to a plurality of users. One example is a social networking application. For example, without limitation, a dating service may allow the plurality of users to enter individual preference information associated with a desired characteristic of a mate. Processing of the aggregate data 102 may allow the service to recognize when pairs of mutually desirable mates are in close proximity of each other. Data associated with this recognition may be transmitted to one or both users in the pair, allowing the users in the pair to meet each other. This transmission of data may be in the form of an alert, such as a text message, e-mail, automated telephone call, and so forth. For another example, an interested-based social network application may allow the plurality of users to enter individual preference information associated with a favorite pastime, such wine tasting, Processing of the aggregate data 102 may allow the service to recognize when events associated with the favorite pastime are being held in proximity to the users. Relevant users may be notified and additional information, which may encourage social interaction between the users, may be provided to users on the basis of the contents of the aggregate data 102. For example, a subset of users may, based upon observed travel patterns in the aggregate data 102, be likely carpool candidates to a local wine tasting event.

Generally, in embodiments, the aggregate data 102 may be disaggregated, scrubbed, reformatted, transmitted as-is, stored, processed, and/or formatted in any practicable manner that is useful to any particular third-party application. Moreover, in embodiments, an alert may be transmitted to a user, wherein the alert comprises data that is associated with a recognition that is associated with some form or component of the aggregate data.

One consideration in the design of the portable electronic facility 300 may be battery life. There are a number of factors that may affect battery life. One factor may be the power density of the battery. Another factor may be the volume of the battery. Yet another factor may be the power consumption of the portable electronic facility 300 connected to the battery. In the portable electronic facility 300, it is typical for the power consumption to be dominated by RE transmission electronics that may be integral to the facility 300 and of which the data communication facility 610 may be comprised. This is due to theoretical and practical limitations of the physics of RF transmission. The battery life of the portable electronic facility 300, then, may be improved by limiting the amount of time that the portable electronic facility 300 is transmitting data: the transmission electronics may be powered down the rest of the time. Likewise, it is known that the power consumption of RF receive electronics, of which the data communication facility 610 may also be comprised, may have a considerable impact on the battery life of the portable electronic facility 300. It follows that methods for limiting the amount of time that the portable electronic facility 300 is sending and/or receiving data may be present in some embodiments of the location services facility. These methods may comprise varying the length and/or frequency of transmissions to and/or from the portable electronic facility 300.

Another consideration in the design of the portable electronic facility 300 may be a speed with which the facility provides the user with data and/or the accuracy of the data. In embodiments, the portable electronic facility 300 and/or the location services facility at large may be designed to vary the length and/or frequency of data transmissions to and/or from the electronic facility 300 to improve the speed with which the facility 300 provides a user with data and/or the accuracy of the data.

One aspect of the location services facility is to provide location information to the user. Location information may comprise latitude; longitude; altitude; depth; pitch; roll; yaw; time; velocity; or orientation and/or distance to or from a waypoint, an origin, a destination, magnetic north, or true north. The location may be presented to a user in a number of embodiments including, without limitation, a map, a moving map, an interactive map, a textual description, a spoken description, a color code, an aural code, an e-mail, a text message, a pager message, a printout, and so forth.

The location information provided by the location services facility to the user may originate from the use of various methods incorporating data from a sensor facility such as, without limitation, a global positioning system (GPS), a radio frequency identification (RFD), a plurality of cell phone towers (for example, for time and/or triangulation), an altimeter, a depth gauge, a gyroscope (including “gyroscopes” that use a vibrating structure, a laser, or a MEMS device), an inertial sensor, a compass, an accelerometer, a speedometer, a seismometer, a magnetometer, a thermometer, a photon detector (including, but not limited to, a visible camera, an infrared (IR) detector, an ultraviolet (UV) detector, an X-ray detector, a gamma-ray detector, a Geiger counter), a hygrometer, a heart rate monitor, a blood glucose meter, a blood oxygen meter, an electrical sensor, an electrical interference sensor, a current sensor, a resistance sensor, a thermistor, an electrostatic sensor, a frequency sensor, a temperature sensor, a heat sensor, a thermostat, a differential light sensor, an opacity sensor, a scattering sensor, a diffraction sensor, a refraction sensor, a reflection sensor, a polarization sensor, a phase sensor, a florescence sensor, a phosphorescence sensor, an optical activity sensor, an optical sensory array, an imaging sensor, a calibrated micro mirror array, a calibrated pixel array, a micro mirror array, a pixel array, an angular momentum sensor, a rotation sensor, a rotation speed sensor, a rotation direction sensor, a velocity sensor, an inclinometer, a momentum sensor, a smoke detector, a fire sensor, a heat detector, a combined heat and smoke detector, a vapor sensor, a gas sensor, a signal sensor, a wireless signal sensor, a cellular signal sensor, a Wi-Fi signal sensor, an Internet signal sensor, a touch sensor, a contact sensor, a viscosity sensor, a position sensor, a height sensor, a ray detector, a microwave sensor, a proximity sensor, a distance sensor, a motion sensor, a range sensor, a mote, a marker, a powered marked, a signal emitter, a signal receiver, a powered signal emitter, a powered signal receiver, a chemical sensor, a fire sensor, a hazardous material sensor, a hazardous vapor sensor, a biohazard sensor, a bacteria sensor, a virus sensor, an anthrax detector, a nerve gas sensor, a poisonous gas sensor, a carbon monoxide detector, an energy sensor, or an aerosol sensor. RFID tracking may, without limitation, comprise a portable electronic facility further comprising a RFID transponder that is interrogated by electronic equipment that is installed along a roadway, along a sidewalk, at the entrance of a building, at the egress of a budding, or in a building. Once created, the location information may be compiled, accessed, processed, searched, sorted, or in any other way manipulated for the benefit of the first end user 202, the second end user 204, or any other entity that values the user's location information. In embodiments a location may be obtained from a database, such as based on the location of a wireless access facility, such as a Wi-Fi or 802.xx access point, switch, or similar device.

In embodiments, an individual location information sample, which may be a datum 104, may be subject to errors, which may be due to physical or practical limitations of the location services facility. For example, cell phone triangulation systems are limited by RF multipath effects due to large metal structures such as building or water towers. One method of compensating for these errors may comprise processing multiple location samples to determine, via statistics or heuristics, to what extent the individual location information sample may be reliable. Another method of compensating for these errors may comprise processing multiple location samples to determine an aggregate location information sample that may include information such as mean location and standard deviation, which may provide a more accurate determination of location than the individual location information sample.

Referring now to FIG. 7, the portable electronic facility 300 may comprise a state machine 702 heuristic approach to obtaining a GPS fix 700. The state machine 702 may comprise a plurality of states, 704, 708, 710, 712, 714, and 718. The state machine 702 may comprise a fix delay, which may be a string that may be processed by the central processing unit 612, the operating system 614, the software application 618, the geolocation facility 620, or any other facility associated with the geolocation. facility 620. In the plurality of states, “mposition:delay=tow” may indicate a fix delay that may take no greater than 32 seconds to provide a limited degree of computation for determining a low-accuracy velocity of the portable electronic facility 300. “mposition:delay=high” may indicate a fix delay that will take no greater than 3 minutes and 32 seconds to provide a substantial degree of computation for determining a high-accuracy velocity of the portable electronic facility 300.

The Inside State 704 may reflect that the facility 300 may be receiving the GPS fix 700 from a tower. In this state, the facility 300 may sleep for 90 seconds and then may attempt to receive a fix, at first, using mposition:delay=low and then for every fix thereafter using mposition:delay=high. Should the facility 300 receive five fix attempts in the Inside State 704, the facility 300 may go into the Sleep State 704.

The Stopped State 710 may reflect that the facility 300 may be receiving the UPS fix 700 from a satellite and that the facility 300 may be associated with a speed, according to the fix's National Marine Electronics Association's (NMEA) string 720, of approximately 0 kilometers per hour (KPH). In this state, the facility 300 may sleep for approximately 90 seconds and then may attempt to receive a fix using mposition:delay=high. Should the facility 300 receive five sequential GPS fixes 700 in the Stopped State 710, the device may go into the Sleep State 704. In the Stopped State 710, the facility 300 may send every UPS fix 700, of which a datum 104 may be comprised, to a datum receiving facility, which may, without limitation, comprise the database 100, the application server 108, the Web server 110, another portable electronic facility 300 such as via the P2P network 304, or any other facility associated with the database 100 or the distributed database component 302.

The Moving_Slow State 712 may reflect that the facility 300 may be receiving the UPS fix 700 from a satellite and may be associated with a speed, according to the fix's NMEA string 720, of greater than approximately 0 KPH and less than approximately 17 KPH. In this state, the facility 300 may sleep for 60 seconds and then may attempt to receive the UPS fix 700 using a mposition:delay=high and every UPS fix may be sent to the datum receiving facility.

The Moving_Med State 714 may reflect- that the facility 300 may be receiving the UPS fix 700 from a satellite and may be associated with a speed, according to the fix's NMEA string 720, of greater than approximately 17 KPH and less than approximately 106 KPH. In this state, the facility 300 may sleep for 30 seconds and then may attempt to receive the UPS fix 700 using mposition:delay=high and every UPS fix 700 may be sent to the datum receiving facility.

The Moving Fast state 718 may reflect that the facility 300 may be receiving the UPS fix 700 from a satellite and may be associated with a speed, according to the fix's NMEA string 720, of greater than approximately 105 KPH. In this state, the facility 300 may sleep for 10 seconds and then may attempt to receive a GPS fix 700 using mposition:delay-thigh and every UPS fix may be sent to the datum receiving facility.

The Sleep State 704, as is mentioned above, may reflect that the facility 300 may have received five UPS fixes in a row in the Stopped State 710 or may have receive five GPS fixes in a row in the Inside State 708. In this state, the device may sleep for approximately two minutes and then attempt to receive a UPS fix 700 alternating with the use of mposition:delay=high and mposition:delay=low.

The state machine may also note a significant position change wherein a new UPS fix may generate a measured change in distance of greater than 10 kilometers. A check for the significant position change may be taken on every UPS fix 700 in the Sleep State 704 or Inside State 708.

When the portable electronic facility 300 is switched into an operational mode, the facility 300 may make an attempt to retrieve a UPS fix using an mposition:delay=low, If the facility 300 cannot receive a satellite UPS fix 700 on a first fix attempt, the facility 300 may immediately or soon thereafter make another attempt to receive a UPS fix 700 using mposition:delay=high. In either case, the facility 300 may consequently be considered to be initialized.

The facility 300 may, based upon its current state, make attempts to receive the UPS fix 700 at a rate, which may be periodic. In the event that the UPS fix 700 cannot be obtained or is invalid, the facility 300 may alert a user of the facility 300. In the event that a valid UPS fix 700 cannot be obtained during five consecutive attempts, the facility 300 may discontinue attempts to get the UPS fix 700, which may necessitate a manual restart of the facility 300 to renew attempts to obtain the GPS fix 700.

Once obtained or calculated, the location information, which may comprise the GPS fix 700, may be used in an application service including, but not limited to, an entertainment application service such as location-aware games, a commerce application service such as location-based transactions, an information application service such as mapping a route from an origin to a destination, or any other application service specified, mentioned, implied, or made apparent by this discussion.

Referring now to FIG. 9, as mentioned above, the location services facility may support a geofencing application that involves the geofence 900. In one case, the geofence 900 is the circumference of a circle that is defined by a user who specifies a geographic location 902 for its center and a radius, In general, the geofence 900 may be defined as any arbitrary boundary between one geographic area and another, wherein the boundary may be stationary or may move, wherein said movement either may be correlated to the movement of a physical object such as the portable electronic facility 300 or may be determined arbitrarily. In any case, the geofencing application may be the alert application and, therefore, may generate the alert when the portable electronic facility 300 crosses the geofence 900. This alert may be transmitted to the user who specified the crossing of the geofence 900 as an alert-generating event. Alternatively or additionally, this alert may be transmitted to a second user who either opted to receive the alert or who was designated to receive the alert. Optionally, the alert may pertain to a facility in the vicinity of the geofence 900, such as and without limitation an advertisement for a nearby restaurant.

In embodiments, the user may define and/or manipulate a geofence 900 via the Web browser of the three-tier architecture. Alternatively, the user may define and/or manipulate a geofence 900 via the portable electronic facility 300, for example and without limitation via the input facility 608 of the portable electronic facility 300.

The location services facility may support a number of end uses. One end use may comprise a location based adaptable user interface. For example, in an embodiment, the portable electronic facility 300 may be a cell phone. A screen integral to the cell phone may display information to the user of the cell phone. Under usual circumstances, the screen may display a small menu of options, such as show location and get directions. However, when the cell phone is within proximity of a restaurant, the screen may display an additional menu option make dinner reservation. This adaptation to the menu of options is an example of a location based adaptable user interface.

Another end use may comprise the tracking of the location of the portable electronic facility 300, which has been described above.

For example, a comprehensive stop report provided by the location services facility may comprise a plurality of entries comprising a stop identification, a time, a duration, and a location. The stop identification may comprise a unique identifier comprising a number associated with a stop made by a delivery truck. The time may be associated with a time at which the delivery truck stopped. The duration may be associated with the time that the delivery trucked dwelled at the stop. The location may be associated with the geographic location of the stop. In total, the comprehensive stop report may provide information useful to an operator of a business in monitoring the performance of a flea of delivery trucks.

Still yet another end use may comprise remotely affecting the portable electronic facility 300. In one embodiment, the location services facility may start, stop, or change an application on the facility 300. The application may comprise, without limitation, un/up, a route, a to-do list, a calendar, a calculator, an expense report, a mileage tracker, a phone book, and so forth,

Another end use may comprise outputting location information on the portable electronic facility 300. As is mentioned above, the portable electronic facility 300 may provide to the user location information associated with the portable electronic facility 300, for example and without limitation, information in the form of a map. The portable electronic facility 300 may augment the information provided by the location services facility with information from the sensor. For example, the location services facility may provide mapping information to the portable electronic facility 300 according to the location data provided by the facility 300 to the location services facility. Upon this map, the facility 300 may overlay an artificial horizon, which provides pitch and roll information to the user. This pitch and roll information may be provided to the portable electronic facility 300 by the sensor.

Yet another end use may comprise outputting location information on the portable electronic facility 300, wherein the location information itself depends upon the output sensor. For example, in an embodiment wherein the sensor is a visible camera, images of surrounding terrain may be captured by the camera and may be transmitted to the location services facility. The location services facility may analyze these images and transmit location information associated with the images back to the portable electronic facility 300. This location information may then be output by the portable electronic facility 300 for presentation to the user.

More generally, a plurality of end uses may comprise presenting location based information to the user in response to the characteristics of a location, In one embodiment, as described above, the characteristics of a location may be the terrain in the vicinity of the location. in other embodiments, the characteristics of a location may, without limitation, comprise the barometric pressure, humidity, temperature, radioactivity, depth, infrared lighting, visible lighting, ultraviolet lighting, and so forth.

Another end use may comprise providing location information associated with a transaction, In one embodiment, a person may present a credit card associated with the user to a merchant at a point of sale. The merchant or merchant's bank may query the location services facility to determine the location of the portable electronic facility 300 associated with the user. If the portable electronic facility 300 is located at the merchant then the user may be presumed to be located at the merchant and the person may be presumed to be the user. Therefore, the transaction may be authorized. Conversely, if the portable electronic facility 300 is located at a location other than at the merchant then the location of the user may be deemed to be in question and the person is may not be deemed to be the user. As a result, the transaction may be denied or the merchant may be required to further verify the identity of the user.

Yet another end use may comprise tailoring information to the behavior of a user. In one embodiment, the location services facility may recognize that the route a user usually takes to and from work is suboptimal. In response to this behavior of the user, the location services facility may provide to the user a custom tailored, daily-commute route map.

More generally speaking, end uses of the location services facility may provide information to the portable electronic facility 300 based on information received from the portable electronic facility 300, including but not limited to information associated with the user's behavior.

In applications, the location tracking facility 1200 may be used by families to track members of the family, such as children or elderly members of the family. For example, in tracking the location of a child, the tracking may identify a position, within a yard, upon the activation of certain triggers, such as upon request by another family member, if the child is lost, and/or only at specified times such as a day of the week and/or time of day. For example, in tracking the location of elderly, the tracking 1200 may be in a home, in a hospital, and/or in a care facility.

In other applications, the location tracking 1200 may be used to track driving and/or vehicle location. This tracking 1200 may comprise tracking location 1202, speed, and/or a set path. An alarm, which may be an alert, may be sent when the driving is classified as speeding. An alert may also be sent if the vehicle position is outside a boundary, wherein the boundary is associated with shipping a hazardous material. In some applications, the location tracking may encompass the vehicle location of every vehicle in a fleet.

In general applications, the tracking 1200 may be remotely set, permanently enabled, and/or disabled only from a remote location. Thus, the portable electronic facility 300 may be controlled remotely, which may include the remote control of an application (such as and without limitation software application 618) within the portable electronic facility 300.

In yet another application, the tracking 1200 may be used for computer gaming, wherein one or more features of the game may be based on the real-world location 1202 of the portable electronic facility 300. In embodiments the real-world location 1202 of the portable electronic facility 300 may be used to trigger other actions or events within the game. In such embodiments, the real-world location may be led to a program or system that generates game conditions based on the location, such as from a table, database, or other facility, or based on real-world information associated with the location, such as weather information, stored views of the location, maps of the location, or the like. For example, the current weather conditions in the environment surrounding the portable electronic facility 300 may be retrieved from a server that obtains weather information, and a game operating on the portable electronic facility 300 may present similar conditions to the user of the portable electronic facility 300, such as in a role-playing game, a driving game, first person shooting game, or other simulation game. Similarly, a map for area surrounding a user may be used to generate a simulated environment in the game that resembles the user's real world environment. For example, locations of buildings and roads can be used to create a “track” in a driving game, or to create obstacles or locations in a role-playing game. In embodiments locations of other portable electronic facilities 300, such as those used by friends or family members of a user, can be used to generate game elements, such as to allow users to “race”, “battle”, or otherwise interact in a multi-player game that draws elements such as weather, roads, or buildings from the real-world environments of the users of the portable electronic facilities 300. Thus, in a variety of embodiments, a game on a portable electronic facility 300 may be location-based.

In still another application, the location tracking 1200 may be used as a basis for selecting entertainment such as determining available shows, movies, and/or food facilities. For example, a menu of video or movie clips may be made available based on the location of the portable electronic facility 300, such as showing movies that contain scenes that depict areas that are in proximity to the current location of the facility 300, showing tourist information for the area near the facility 300, or the like.

In still yet another application, the tracking 1200 may be associated with a police activity, such as, without limitation, tracking shoplifters, tracking criminals, placing a portable electronic facility 300 in a money bag, and/or placing a portable electronic facility 300 in a bank teller drawer.

For example, a geofence may be established around a particular location, so that an alert is sent if a person exits the area of the geofence, such as if a home health care worker leaves a scene, a worker enters a hazardous area, a shipment departs from a planned route, a social worker fails to appear at a designated location for an appointment, a maintenance worker fails to appear at a designated location, or the like.

In still another application, the tracking 1200 may be associated with a pet, such as and without limitation tracking the pet within a yard and/or if lost. A geofence may be established around the pet, so that an alert is sent if the pet departs the region of the geofence.

In yet still another application, the tracking 1200 may be associated with a school, such as and without limitation tracking students and/or employees at all times and/or only if they leave school property. A geofence around the school can allow a teacher, administrator or parent know when a child arrives at the school, leaves the school, or the like. Thus, portable electronic facilities 300 can be used to check attendance against the rolls of the school, and to determine the locations of absent students who possess such portable electronic facilities 300.

In an embodiment, the tracking 1200 may be associated with health care, such as and without limitation tracking patients, doctors, and/or nurses. In this application, the tracking 1200 may be within a health care facility, outside a health care facility, and/or may comprise finding the closest doctor and/or nurse in an emergency. A geofence may be established, for example, indicating when a patient has left a hospital, or indicating when a doctor arrives or departs the proximity of the facility, such as to generate an alert if there are no enough staff available to handle an emergency.

In another application, the tracking 1200 may be associated with real estate, such as, without limitation, tracking a location of a house for sale, which may be associated with a picture, directions, and/or tracking visitors to the real estate. For example, a portable electronic facility 300 may be associated with a digital camera, and the location of a picture or recording, as determined by the tracking facility 1200, may be embedded in the picture or recording for future retrieval of the location of the picture. Such a picture or recording location capability may be used to know the location of a real estate location, the location of an accident, the location where a photo was taken during a vacation, the location of a crime, or the location of another event that is recorded on the digital camera.

The capability to record the location of a picture or a recording may support transport logistics, the adjustment of traffic signals, the documentation of potholes, the documentation of defects in infrastructure, and/or an insurance purpose. The insurance purpose may comprise documenting the location of accident; capturing a picture or recording of an accident such as for the purpose of adjusting claims; storing driving habits on file such as for the purpose of determining safe driving, which may be associated with changes in insurance prices based on driving speed. The picture or recording location tracking may support bounty hunters, private investigators, police, detectives, or other in, for example, tracking people.
